摘　　要：以整棉仁为原料,利用油脂浸出工艺,进行破碎、软化、轧坯和萃取得到高蛋白的棉粕。通过单因素实验考察了整棉仁16目筛透过率、软化时间、正己烷萃取次数和正己烷萃取料液比对棉粕质量的影响。结果表明:整棉仁破碎至16目筛透过率10%~20%,在90℃条件下软化60 min,进行溶剂的多次萃取,可得到粗蛋白含量为60%~62%的棉粕。Using oil leaching process,cottonseed meal with high protein content was obtained by breaking,softening,flaking and extraction with whole cottonseed kernel as raw material. The effects of 16 meshes screen transmittance of cottonseed kernel,softening time,extraction times and solid-liquid ratio of n-hexane extraction on quality of cottonseed meal were investigated by single factor experiment. The results showed that the whole cottonseed kernel was pulverized that 10%-20% cottonseed kernel could go through 16 meshes screen,softened at 90 ℃ for 60 min,and then extracted for multiple times,and the cottonseed meal with 60%-62% crude protein content was obtained.
